I'm now tackling the detailing and painting of my K car's original K motor. It's a San Jose car with a assembly date of 2.16.1965. What I want to confirm before stripping and applying the black paint to the motor's intake manifold is whether the manifold's cast number is correct for the car's time line. Here's the #: C5OE-9425-C. I know the C5 indicates 1965, but I don't know what the numbers that follow indicate, or if a February 1965 K car would have been equipped with a C4xx-xxxx-x intake, not a C5xx... intake. Thanks again for any input. Ron

C5OE-9425-C is the Ford part number in raised letters marked on the manifold which is valid for your engine's time period. Why would you think you used a C4xx part number? That intake is the standard one for all 4 barrel carburetors, nothing special. It uses a water outlet with a recess for the thermostat.

Thank you, Jim. BTW, I thought some of the cars coming off the line early in '65 may have been equipped with "carry over" intake manifolds from 1964. Ron...

Autolite: Thanks for the information. My intake (C50E9425-C) has the date stamp you posted, i.e. 5A25. This converts to January 25, 1965 which I consider correct for my car's projected assembly date of February 16, 1965. What do you think? Thanks, Ron

What's the assembly date of the motor?

A valid point. Consider that the 289 HP engine was the premium engine for Mustangs and would most likely get the latest released components, manifolds included.

Yes, and I double checked the casting #s this afternoon. This is what is cast (not stamped as I believe someone earlier suggested they were) on the block above the starter motor: C5AE-6015E. And above that, also cast not stamped, is the date 5B5 (February 5, 1965). So I have an intake manifold on my K motor with a date stamp of 5A25 (January 25, 1965) and a K motor with a cast date of 5B5 (February 5, 1965). So unless I'm missing something (not an unknown experience), the intake can be consider correct for the motor. What do you think? Thanks, Ron. p.s. Forgot to add that the car's scheduled assembly date is February 16, 1965).

Scheduled built date means little. Normally what is most important to this discussion is your engine assembly date that you've been asked for above. But given the fact that the intake casting proceeds the block casting date by a little over a week or so it’s likely going to pass scrutiny given what we know at the moment

Sorry I'm late responding to the Qs in the post I started, but I got called away on some work issues. As to my K block's assembly date, whoever was on the line that day had a weak swing. The only thing I can vaguely make out is the top of what appears to be a 5. Disappointing, but probably not the first time this has happened. I'll keep going on this "interesting" re-assembly and will surely be back with more Qs. Thanks to everyone for all the helpful information. Ron...

The date is also stamped on the inside of the block where the pan bolts to. Not sure if you currently have the oil pan attached or not. Maybe he had a better swing there...

Here is an example from my 1964 1/2, although not exact to your Feb. 65'. As you can see by the pics, the front of the block was stamped 4F22, 1964, June 22nd. As ChrisV289 stated, the other stamping is found under the oil pan. In my case, at the rear of the block. I circled the same date, stamped 4F22. Hope this helps you.
-
For some reason the site will not take the other pic. let me look into it..

Ah-ha, had to downsize the image. Here you go..

To Chris V 289: The pan is on the motor, but it will be coming off soon. Could you let me know more specifically where to look for the motor's assembly date when I remove the pan? Thank you! Ron (also, see my response below to HiPoGiddyup).
To HiPoGiddyup: My casting numbers on the block behind the starter motor are very clear and easy to read. But the motor's assembly stamp on the left/front of the block is no where near as clear as your 4F22F stamp. As I said in my earlier post the only number that I can just begin to make out is the first one which appears to be a 5. At first I thought it was illegible because the person making the stamp just did a poor job, but a friend of mine who's a part-time machinist looked at it and said he thinks there was a legible stamp there at one time, but a PO apparently had the motor rebuilt at one time and the block was "shaved" slightly to ensure a square fit with the head. To me that makes sense, but either way I'll probably never know the assembly date unless there's a second one to be found when I remove the pan as Chris V 289 indicates in a post just above yours. I'll report back here when I get the pan off next week. Thanks for all the help, everyone! Ron

Should be near the back right where the pan meets up. This is a pic off Charles' blog when he did the K code.
-
Chris: Wow, that picture is a great help and a greater stimulus to get that darn pan off. Many thanks! Ron...

To 65 Autolite: Sorry I'm late getting back to you regarding the thermostat "pocket" question. My intake manifold has a cast date of 5A25, or January 25, 1965 (my car's scheduled build date is February 16, 1965). The intake manifold has a recessed “lip” all the way around the inside perimeter of the thermostat “pocket,” which is obviously where the thermostat fits. And the matching thermostat "cover" has a perfectly flat surface. Of interest, I have another manifold on the shelf (5H24/August 24, 1965) that has only a flat surface around the perimeter of the manifold's thermostat “pocket,” but a recessed lip around the inside perimeter of the thermostat "cover" that bolts onto the manifold. Thanks, Ron...

To 65 Autolite: No problem. Below is a nut-shell description of the two manifolds. #1 is currently on my K motor; #2 is from an intake that's been on a shelf in my garage for so long I have no memory of where it came from:
1. Date: 5A25
Casting #s: C50E-9425-C
2. Date: 5H24
Casting #s: C60E-9425-B
If you want pictures of the two, let me know and I'll see if I can post them.

Confirming the intake manifold differences, this example being the water outlet. Note the transition date.
I think that there is a water outlet missing from the list. A version that is the same as the C9OZ-8592-A in cast iron but without the tapped hole for the temperature sensor, just a blank pad on top. I had one on a 67 "A" code I sold (it went with the car). I assume it was a Ford part introduced in 1967 but I'm not sure.
